What mouse do you use with your Mac Book Air? I'm looking to buy a mouse and want some suggestions. Magic Mouse is the obvious choice and I already know about that, but I'm not sold on it, so I guess this is a thread for Magic Mouse alternatives. I really like the concept of Microsoft's Arc Touch Mouse. It's easily the most portable mouse I've ever seen because it becomes completely flat when you straighten it. Unfortunately, there are two things wrong with this mouse: 1. It doesn't support mac by default (although many users have gotten it to work) 2. It doesn't interact with the laptop's bluetooth but requires a separate bluetooth USB chip.
